Power VR MBX graphics core
The Power VR MBX graphics core provides fixed function graphics support and is the graphics core utilized in a number of SOC designs, including the Texas Instruments OMAP, Intel ATOM, and Freescale 5121, 512x and i.mx. There are over 45 MBX enabled handheld devices in use worldwide, more than 40 million of which contain hardware accelerated graphics.
ALT Power VR MBX Drivers
OpenGL ES 1.1
OpenVG 1.1 driver libraries
- Provides support for a number of real time operating systems and embedded systems
- Customizable drivers take advantage of graphics engine and SOC design
- Includes ALT’s proprietary Target Area Render (TAR) to enhance Window Rendering
- An add-on from ALT Software that allows applications to render only a specific region
- Enables fast viewport rendering
- Allows large resolution MBX displays to run at 60+ FPS (the MBX driver alone without the TAR add-on can reach only about 30 FPS at a 1024x768 screen resolution)
- An OpenGL extension that can be added into the Extensions manager within the SDK
- Function prototype is glTargetAreaRenderALTEXT (GLint x, GLint y, GLuint width, GLuint height) - x and y are the positions you want the output to appear on screen, in pixels
ALT Target Area Render (TAR)
